For the location of the slot numbers, see "DIMM slots (on page 12)."
This multi-channel architecture provides enhanced performance in Advanced ECC mode. This architecture
also enables Lockstep and Online Spare Memory modes.
DIMM slots in this server are identified by number and by letter. Letters identify the population order. Slot
numbers indicate the DIMM slot ID for spare replacement.
Population order
For memory configurations with a single processor or multiple processors, populate the DIMM slots in the
following order:
• LRDIMM: Sequentially in alphabetical order (A through L)
• RDIMM: Sequentially in alphabetical order (A through L)
• UDIMM: A through H, sequentially in alphabetical order. Do not populate DIMM slots I through L.
After installing the DIMMs, use RBSU to configure Advanced ECC, online spare, or lockstep memory support.
